b To all whom it may concern: v Be-it. known that I, BURNHAM O. STICK- NEY, citizen of the United States, and resident of Elizabeth, in' the county of Unionand' State ofNew Jersey, have invented cer-. r

and some'operators are annoyed by this constant movement of the ribbon vibrator; the

operators' vision being directed ordinarily during the actuation of the machine, to the printing point and consequently towards the moving vibrator.

The object of my invention is to provide a construction wherein the parts may be readily set to effect a movement of the ribbon vibrator in the ordinary manner to cover and uncover the printing point at each print-.

ing operation or so that the vibrator-may remain fixed duringthe actuation of the machine and act as a mere ribbon guide, without, however, destroying the visible writ-- ing feature of the machine, thereby overcoming the objection that some operators have to the dancing of the vibrator in the path ofthe operators vision.

To theabove and other ends which wi hereinafter appear, my invention consists in the novel features of construction, arrangements of parts and combinations of devices to be hereinafter described and particularly pointed out in the appended claims.

In the accompanying .drawings, wherein like reference characters indicate corresponding parts in the various drawings, Figure 1 is a central, vertical, front to rear sectional view of one form of typewriting machines embodying my invention. Fig. 2 is a vertical, transverse, sectional view of the same, the section being taken on the line ma: of Fig. 1. Fig. 3 is a diagrammatic side elevation of a portion of the machine, the view illustrating the parts so disposed that the ribbon vibrator is actuated at each depression of a key lever. Fig. 4 is a like view of the same, illustrating a disposition of the parts which normally maintains the ribbon vibrator at the printing point and preventsan actuation thereof during the operation of sectional view of the same,

tion of parts of the mec the inachin'e. "Fig. 5 is a central, vertical,

front to rear sectional viewof a typewrit'ing machine, illustrating another form of my invention. Fig. '6 is a vertical, transverse, thesection being takenthrough the keyboard of the machine and the type actions being omitted. Fig. 7

is an enlarged, detail, pers ective viewof the ribbon vibrator illustrate in' Fi s. 5 and 6, together with certain of the associated mechamsm. Fig. 8 is a fragmentary side elevaanism shown in Fig. 5, the view illustrating the disposition of the parts when the r-ibbonvibrator is maintained at the cprinting point.

1 in icates the base of the machine which is provided with'upwardly extending cornerposts 2 that are surmounted bya to plate- 3, the latter supporting traverse rai s4 von which the carriage 5 travels from side to side of the machine. The carriage has a platen 6. mounted to revolve therein and a feed rack 7 is carried by the carriage and cooperates with a feed pinion 8- mounted on a shaft that is carried in a bearing 9'secured by screws 10 to the top lateof the machine. end of the shaft carries an escapement wheel 11 which'i's operatively connected thereto byfthe usual pawl and ratchet mechanismcontained within a housing 12 and the escapement wheel cooperates with the feed, dogs 13 and 14 carried by a rocker arm 15 so The rear mounted upon a rock shaft 16 and having a coiled spring 17 secured at one end thereto, as indicated at 18, the opposite end of said spring being adapted to bear at 19 upon a' portion ofa fixed'bracket plate 20. .Key evers 21 are pivoted at 22 to the base of the machine and each of the levers is [provided with the usualfinger key 23 an restoring spring 24. I

In-Figs. 1 to 4 of the drawings, each of the key levers has pivoted thereto at 25 an. upwardly extending link 26' that ispivoted at with t its upper end 27 to a bell crank lever .28

pivoted at 29 to asuitable hanger or stud that projects from the forward face of a type bar segment 30. Each .bell cra'nkleveris provided withsegmentalteethiil that 00- .1

operate with segmentally arranged teeth 32 formed on a'type bar 33, which type bar is pivoted at134 to a'studiorhanger'35 projectlng forwardly from the ty ebar segment. It will be understood thatt e type bars are segmentally arranged and are adapted to forth movements by at strike upwardly and rearwardly to the printing point, as indicated in dotted lines in Fi v Fxtending transversely beneath the various key levers is a universal bar 36 that is connected to upwardly extending arms or links 37 pivoted at 38 to a transverse bar 39- whereas the link is pivoted at its upper end 45 to one arm of a bell crank lever 46, the other arm 47 of said bell crank lever being upwardly directed. This bell crank lever is secured to a rock shaft 48 that extends transversely of the machine and is mounted to rock in suitable bearings 49 depending from the top plate andsecured thereto by screws 50. v

Secured to the rock shaft 48 and about midway of the machine is a forwardly extending crank arm 51, the free end of which is provided with a laterally projecting pin 52 that extends into a slot 53 in a vertically movable ribbon vibrator 54. In the present instance, this vibrator consists of a stem-like ortion to which the arm 51 isconnected and rom which extends. a yoke 55, each arm thereof being slotted as indicated at 56 for the reception of the ribbon 57. The slots 56 extend vertically so as'to maintain the ribbon vertically disposed and a side wall of each slot 56 is cut away at 58, for the introduction or withdrawal of the ribbon. It

should be understood, however, that the form of the ribbon vibrator may be varied at will. The arms, which constitute the yoke of the vibrator, extend 'throughvertically disposed bearings or uides 59that are secured by screws 60 to t e top plate of the machine.

Extending fore and aft of the machine beneath the top late is a push rod 61 provided with a pus key 62 at the outerejnd thereof, this rod being adapted to slide longi-v tudinally in a bearing 63 and in an aperture formed in thedownwardl projecting flange of the top plateand w ich constitutes a bearing forthe outer end of the rod. -A

friction sprin 64 is secured by a screw 65 to the bottom 0 the top plate and bears at its free end against the push rod, thus Thainit 'in the position to which it is tainin move The rod is limited in its back and or pins 66 located on opposite sides of the. caring 63 in which the rod is supported and against which the normal indicated in Fig. 3, the end of-the ro will be removed from and maintained out of the path-of movement of the arm 47 of the bell crank lever 46. From a comparison of Figs. 1 and 4, it will be observed that when the push rod is in the position indicated in Fig. 1, the disposition of the in and slot connection 41- 42 between t e transverse bar 39 and the link-'43 is such that the pin will be normally maintained seated in the upper portion of said slot.

Fig. 1 represents the normal positions of 'the partswhen the ribbon vibrator is .adapted to be moved at each printing operation so that the ribbon will be interposed in ;the path of the 1: pc as it is moved to the iprrinting point an will be withdrawn thereom. as the type bar assumes its normal' :position. From an examination of Fig. 3, ;1t will be seen that a depression of a key lever will cause the transverse bar 39 to be depressed to actuate the escapement devices in the usual manner and that this movement will be transmitted from thetransverse bar 39, which inreality constitutes a part of the escapement mechanism, to the bell crank ilever 46, rock shaft 48, and crank arm 51 to Imove the ribbon vibrator so as to effect an interpositioning of the ribbon in the path of the type. When pressure on the finger key is released, the parts will be restored to their positions, illustrated in. Fig; 1 and the carriage will be fed a letter space distance; I

When the operator desires to maintainthe ribbon vibrator at the rinting point and to prevent its actuation uring the operation of the machine, it is merely necessary to push the key 62, thereb moving the push .rod 61 towards the rear 0 the machine and the rear .end of the rod will bear on the arm .47, thus moving the bell crank lever/ 46 and causing the pin 44 to be moved downwardly in its slot 42 and to be normally maintained in this position, asillustrated lin'Fig; 4. If at this time a key lever is depressed, the -transverse bar 39 will be depressed without, however, transmitt' movement to the link 43 and the ribbon vibrator which is connected thereto. The movement of the rod 61 to wards the rear of the machine not only effects a change in the relationbetween the pin 44 andits slot 42 in the manner described, but the same movement is effective to rock the crank arm 51, thereby elevating theribbon vibrator so as to interpose the ribbon in the path of the types and to maintain it in such position. From an examination of Fig. 2,

it will be seen that the ribbon 57 extends.

. maintained in the uppermost position, there is a considerable downward deflection of the ribbon from the vibrator to the ribbon spools, so that only afew' of the .last written letters on a line are covered by the ribbon and that therefore the vibrator may be maintained in position at the printing point without destroying the visible writing feature of the machine. v

In Figs. 5 to 8 of the drawings, I have illustrated another form of mechanism em bodying my invention. Many features of the construction shown in these figures are similar to. the corresponding features rep resented in the patent to Gabrielson No. 662,147, dated Nov. 20, 1900. In this constructioneach of the key levers 21 is pivoted at '68 to a sub-lever 69, the lower end of each of which is slotted at'70 for cooperation with a fixed fulcrum bar or rod 71, whereas the upper end of each sub-lever is' ivoted at 7 2 to a forwardly extending ii 73 that is pivoted at its forward end 74 to a type bar 75, which type bars are mountedin a segment 76 upon a pivot wire 77 carried thereby and the ty e bars are'adapted to vibrate-upwardly and rearwardly to the printing poi'nt.

Pivoted upon the rod 71 is a frame 78 that carries a roller 79 that extends -transversely beneath the various key levers, and constitutes a universal bar with which the key levers coact. The rear end of the frame 78 is connected toan upright link 80 that has the link 80. An upwardly disposed arm 84 ivoted at 84 to the frame 78 and has a 1s I yo e 85 connected thereto which cooperates with an eccentric 86 that is received within the yoke and is secured to a shaft 87 that extends transversely of the machine and is supported in bearings 88. This shaft a bevel. pinion 89 rigidly secured thereto,

which' meshes with a cooperating bevel, pinion 90 that is rotated by the spring drum 91. Projecting upwardly from the yoke 85 is an arm 92, that has a laterally disposed pin 93 projecting therefrom into a slot 94 in a lever 95, that is pivoted at 96 to a stud 97 directed downwardly from the underside of the top plate. The forward end of the lever 95 is rovided with a pin 98 which projects latera ly from each side thereof and'into slots 99 formed by bending the lower portion of the stem 100 of the ribbon vibrator, as clearly illustrated in Fig. 7. A spring 101 is connected at one end to a pin 102 carried by the ribbon vibrator and at its opposite end 103 to the forward end of the lever 95. The ribbon vibrator is provided with a struck up ear 104 that projects rearwardly therefrom and constitutes an abutment with which a cam 105 is adapted to cooperate. This cam is secured to the inner end of a push rod 106 having a finger piece 107 at the outer end thereof, the rod itself being suported in a bearing 108 secured to the cross ar or support 109 that extends across the segment and is secured in place by screws 110. This bar also constitutes a support for the type guide 111 that is grooved in the side edges for the reception of the side armsv and the ribbon vibrator is to be actuated to cover and uncover the printing point at each printing operation, each depression of a key lever will cause the arm 84 with its yoke 85 to be drawn down, thereby depressing the rear end of the lever 95 and causing the vibrator to be moved upwardly into the path of the type as itapproaches the printing point, and when pressure on the finger key is released, the parts will be restored to the normal positions illustrated in Fig. 5, and the carriage will be fed a letter space distance. At each letter s ace movement of the carriage, the sprin rum, which is connected thereto in the usua manner by a band 91 ,W1ll rotate, thereby transmitting movement through the beveled pinions 89 and 90 to the shaft 87 which turns the eccentric 86, thereby moving the yoke fore and aft of the machine around its pivotal connection 84 with the frame 78, so that the pinv93 is moved forward and back in the slot 94 during the operation of the'machine and the pin 93 is moved nearer to or farther.

from the pivotal center 96 of the lever 95 and a variation in the throw of the lever is effected, to ive a slightvariation in the throw of the rib on vibrator, thus moving the ribbon laterally ortransverselyof the platen to dif-' ferent extents during the. operation of the machine, in order to utilize the ribbon widthwise, aswell as longitudinally. When, how ever, the operator desires to maintain the ribbon vibrator at rest, it is merely necessary .to push the fin er piece 107 towards the ribbon vibrator, 5111s moving the push rod 106 longitudinally in the direction of the arrow in Fig. 7, and forcing the cam beneath the abutment 104 on the ribbon vibrator and elevating it against the tension of the spring 101 Without disturbing the actuating lever 95. When the parts have been moved in the manner described, the disposition of the pin slots 99, will normally rest the lower portions thereof, so that a movement of the actuating lever 95 at this time will be inefback to the position indicated in Fig. 7

When this occurs,- the ribbon vibrator will be moved down to the position indicated in said figure by the spring 101 and the disposition of the pin and slot connection between the ribbon vibrator and' its actuatin lever will be again changed to the norma position, so that an actuation of the lever 95 at this time will cause the ribbon vibrator to move up with the free end thereof to cover and'uncover the rinting point at each printing 0' eration, t e spring 101 maintaining the vi rator at all times in position where the pins 98 will be seated in the uppermost portions of the slots 99.

From the foregoing description, it will be understood that in either construction shown and described, the vibrator normally maintains the ribbon away from the printing point to expo'seiit when the parts are set to afford. an actuation of the vibrator at each printing operation, whereas the act of setting the parts so that the vibrator remains at rest during the actuation of the machine is effective to move the vibrator to and maintain it in a position where the ribbon will cover the printing point, or be interposed between the types and the printin pomt, and thatthe re ative disposition of t e parts is changed so that at this time the means for automatically moving the vibrator are ineffective to actuate; that a movement of either the push key 62 or the finger piece 107 is effective to change the position of the vibrator relative to its actuating means; that the vibrator is adapted to be operatively connected to its actuating means or to be thrown out of operative connection therewith that when the vibrator is connected to its actiiating means, it causes the ribbon to uncover the printing point and when the actuator is disconnected from its actuating means, it causes the ribbon to cover the printing point; that the vibrator is adapted to move with or independ-' ently of its actuating means; that means are employed for throwing the connections between theribbon vibrator and its actuating means into or out of cooperativerelation, and that in one case the finger keys are .effective to transmit movement to the vibrator through said connections and in another case they are ineffective for this. purpose; that when said vibrator is maintained at rest, the finger keys, type bars and escapement mechanism ma be moved independently thereof and that the fixed vibrator does not therefore interfere with the actua- What I claim as new and desire to secure.
